NOZZLE Russian patent published in 2018 - IPC A62C31/02 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to spraying of fluids equipment and can be used in fire fighting, agriculture, chemical industry and heat power engineering. In the nozzle, comprising a hollow cylindrical body with a vortex flow divider, an external thread is made at the upper part of the body to connect the distribution pipeline for supplying liquid to the fitting, and in the lower part of the body an external thread is made for connecting with a conical dissector of the vortex flow by means of a ring-shaped casing to which the outer and inner perforated surfaces are attached, wherein in the body there is an inner cylindrical chamber that serves to supply liquid and in which a swirler is arranged coaxially and with a clearance relative to its inner lateral surface, made in the form of a sleeve with a screw external thread with a large pitch of the trapezoidal profile and fixed by means of an internal thread on the rod which is fixed in its upper part by means of a strainer filter to the body, and in the divider porous surface made in the form of truncated ellipsoid of revolution, chokes are made, arranged both vertically and horizontally, and also at an angle of 45 ° to the body axis, at that, the vertically located holes diameter is smaller than the other holes diameters.

EFFECT: high efficiency of liquid atomizing.
